Applicationfiled September 9, 1927. Serial No. 218,383.

This invention relates to machines for making matches, having reference more especially to mechanism for producing strips of match splints from sheet material, such as pasteboard or veneer, my principal object being to provide simple an efficient means whereby such strips are rapidly and accurately produced.

The invention is especially, though not exclusively, designed for use in connection with or as an attachment to a match making machine of the general character illustrated in Letters Patent of the United States No. 636,170, dated October 31, 1899, wherein is employed a suitable chain of strip holding devices operative to carry strips of splints to and through the dipping and other stations.

- This carrier is moved intermittently. and in each, dwell thereof the leading end of a web of match stock, of suitable width, is advanced by intermittently acting'feed rolls into en gagement with one of the strip holders. In each succeeding movement of the web it passes between complementary bar dies in the vicinity of the carrier, which dies, in each pause of the web, are operative to slit the web longitudinally in parallel splint lines and at the same time offset or spread the alternate subdivisions to facilitate the subsequent dipping operations. As each succeeding row of subdivisions is formed the web is severed transversely by a vertically reciprocating knife to produce a leading splint strip having an unslitted marginal portion which is-held in a holder of the carrier.

In the preferred form of embodiment of my invention herein illustrated, a revoluble cutting element for longitudinally slitting the web at spaced intervals throughout is length is arranged between the web feeding means and the bar dies, the latter being utilized as a spreader for alternate splints formed by the longitudinally slitted portions of the web. This cutting element comprises a roll having its axis of rotation longitudinally of the direction of travel. of the web and having peripheral blades parallel to said axis, in combination with means for eflecting relative cooperative movement between the roll and the web, transversely of the latter, so that the blades consecutively incise the web throughout its width in parallel longitudinal lines. Means are provided to effect and ensure the proper registry or timing of the cutter roll at each side of the web, preparatory to each succeed ng revolution of the roll, and the roll is also provided with means for severing the alternate slitted portions of'the web at their trailing ends, which portions are subsequent- 1y spread from the "normal plane of the web.

The invention also comprises novel'fea tures of construction and combinations of parts which will be hereinafter described, the scope of the invention then being defined in the appended claims.

In the drawings- Figure 1 is a side elevation of a portion of a match making machine equipped with splint cutting mechanism embodying my in-' 'vention, the sheetmatch stock being indicated.

Fig. 2 is an enlarged-view of a portion of the mechanism shown in Fig. 1.

Fig. 3 is a plan of the mechanism illustrated in Fig. 1, the reciprocating splint spreading and cutting devices being omitted" 3, but including the reciprocative splint.

spreading and cutting devices.

Fig. 6 is a vertical section through the revoluble cutter and adjuncts, as on the line6-6 of Fig. 4.

Fig. 7 is a vertical section at one end of the revoluble cutter, as on the line 7-7 of Fig. 6, the serrated cutting disk being partly shown in elevation.

Referring to the drawings, 10 designates a suitable supporting frame, and 11 a. power driven shaft journaled in bearings in the frame.

12 designates a portion of an intermittently movable carrier adapted and arranged.

to receive strips of match splints and convey them in spaced parallel relation through succeeding stations for paraflining, heading and drying. The form of carrier herein illustrated comprises an endless chain of recessed links provided at regular intervals with spring clips. 13, which co-act with the adjacent walls of the recesses to afford regularly spacedcard or strip holders, which carrier is o ment, during each pause of the web imposed on the plate 23, t

' of a splint. a0 thereto a cutting geared with and driven from a shaft 14 of the machine in any usual or approved manner.

15 designates a vpair of parallel feed rolls 6 spaced somewhat in front of the strip receiving portion of thecarrier and adapted to engage a web of match stock, as S, and to advance the web intermittently toward the carrier. The shafts 16 of these rolls have n their bearings in suitably disposed boxes on the main frame, and one of the shafts has fast thereon a ratchet 17 with which engages a pawl 18' carried by a crank disk 19 loose on such shaft. This disk is operatively i6 connected b means of a rod 20 with a cran 21 on the s aft 11, and hence the feed rolls are intermittently rotated in the usual man- Fastened on the main frame, in rear of the A) feed rolls, is a horizontal table 22 upon which is supported a plate 23 whereof the upper surface is in horizontal alignment with the bite of the feed rolls and is adapted to receive and su port each succeeding portion of the 1 web w ich is advanced by and beyond the Xr sponding with the dimensions of match splints,

the alternate subdivisions being separated at their trailing ends from the body of the web, as indicated at m, Fig. 3. The

cutting element in its preferred form emvm bodies a roll 24 having-a series of uniformlyspaced (peripheral cutters constituted by the outwar ly rojecting beveled edges 25 of rectilinear lades 26 which are mounted parallel to the axis of the roll in radial slots 45 formed in the periphery of the roll. Each of the blades corresponds in length with that of a match splint and the space between adjacent blades corres onds with the width One en of the roll has affixed disk 27, the outer beveled edge of which is serrated to present a series of uniformly spacedcutting edges 29 in alternation with the spaces between the blades. The opposite end of the'roll 24 has ailixed n5 thereto a gear wheel 30 hereinafter referred to, which, together with the disk 27, is conveniently secured to the body of the roll by means of through bolts 31. (See Fig. 6.)

The cutting element just described is rotatao ably mounted on a cross-bolt 32 between spaced depending lugs 33 formed on a recip-- rocative carriage constituted in the resent instance by a slide 34 which overlies the path of the web and is movable transversely I 06 of the latter. The slide 34, which is mounted the latter and its associated gear 41.

ridging the web, is operatively connected fast on the upper end of a vertical shaft 38 having its bearings in a bracket 39 which is bolted to one side ofthe table 22, whereby when the shaft 38 is rotated the'slide is reciprocated transversely of the web. On the lower end of the shaft 38 is secured a bevel gear 40 in mesh with a similar gear 41 rotatably mounted on a stud-shaft 42 projecting from a bracket on the main frame, and to the hub of the gear 41 is fastened a ratchet 43 with which engages a pawl 44 pivoted on a disk 45 loosely mounted on the stud shaft 42. This disk is operatively connected by means of a rod 46 with the strap of an eccentric 47 fast on the shaft 11, the travel of which eccentricis such as to effect the advancement of the pawl disk 45 through an arc of ninety degrees, the pawl 44 thus engaging the ratchet 43 and correspondingly actuating Thence motion is transmitted-through the ear 40 and its shaft 38 to the crank disk 3 thus reciprocating the slide 34 and the revoluble cutting element in timed relation to the 'intermittent travel of the web of match stock; that is to say, during one pause of the web the roll rotates across the web from one side to the other and ,in the next succeeding pause the roll rotatesreversely across the web, and

so on.

In each stroke of the slide 34 the lIieripheral blades of the revolving cutter ro consecutivel engage the web and slit it longitudinally, t e successive strokes being timed to provide uncut portions of the web in alternation with the rows of incisions, as indicated at 3 Fig. 3. Coincidentally with the slitting of the web the trailing ends of the alter- Inn nate subdivisions are severed by the disk cutter 27 g The ratio of the gearing for-actuating the crank disk and the timing of the ratchet and pawl mechanisms for said gearing and for the feed rolls are such that during each i.

dwell of said rolls the crank disk 37 makes a half rotation, which imparts to the slide 34 a stroke effective to produce a complete rotation of the cutter roll as it travels from one side to the other of the web. The crank disk remains at rest during the next succeeding rotation of the feed rolls, whereupon, while the feed rolls are at rest and in the next succeeding half rotation of the crank disk 37, a reverse stroke is imparted to the slide to effect the return rotative travel-of the cutter roll across the web; and so on.

In order toensure the proper'regist or timing of the cutter roll at each side 0 the web, preparato to the succeeding cross travel of the rol the roll is equipped with the gear 30 previouslymentioned, and at each side of the path of travel of the web is located roll are positioned to engage and incise the web with precision. In the present instance the racks 48 are formed on or secured to one of a pair of horizontal guide plates 49 which v ll) are supported above and in spaced parallel relation to thebacker plate 23, so as to overlie the web of stock, and are properly positioned to permit the free travel of the roll in engagement with the underlying web. 'These plates act as strippers to revent the upward displacement of the we by the rotating cutters during the transverse travel of the roll.

A suitable friction device, for example, a spring pressed pin (Figs. 5 and 6) is preferably slidably mounted in and transversely of the lug 33 adjacent the gear 30, so as to press against the opposing face of the latter.

hus, in case the machine should be run after the web has fully cleared the cutting roll, or

in the absence of the web, the gear 30, together a with the cutter roll, will hold its proper relative position until the gear has reached and engaged a lateral timing rack 48.

The incised portions of the web progress to and across the usual die members located adjacent the carrier 12, which members in clude vertically reciprocative inclined bars 51 which co-act with complementary fixed bars 52 so as to bear upon the alternate endcut subdivisions of the web and bend or spread them from the normal plane of the web preparatory to the delivery of the leading or uncut end of the web to the carrier 12.

The bars 51 depend from a head 53 which is carried by a vertically reciprocative plunger 54 and has a suitably-disposed pendant knife 55 which, in the descent of the plunger, is adapted and arranged to sever the web across the uncut trailing ends of the longitudinally incised portions of the web after the leading end of the web has been inserted in the opposing strip holder of the carrier, thus producing a strip of match splints which is held by and advanced with the carrier, the next succeeding strip holder of the carrier being then presented to the immediately following portion of the web which has been acted upon y the cutting and spreading instrumentalities; and'so on.

While I have illustrated the cutter roll as applied to a machine having co-acting die bars operative to spread the alternate subdivisions or splints produced in the web by the rotative action of the cutter roll, it is to be understood that any other suitable means for spreadingsuch subdivisions may be employed. Indeed, in the broad aspect of my invention a spreading instrumentality may be omitted without departure from my invention, the characteristic feature of which resides in the provision of a revoluble cutter comprising a series of peripheral rectilinear I blades or knives parallel to an axis ofrotation extending longitudinally of the path of the match stock, in combination with means for effecting relative 'co-operative movement between the cutter and the web transversely of the latter, whereby the individual blades or knives operate'consecutively to incise the web in parallel longitudinal splint lines.

In prior constructions wherein a multiplicity of longitudinal incisions, transversely of he web, were produced by reciprocative bar dies, or by a multiplicity ofsimultaneously rotating circular blades havin a common axis of rotation, the fibres in the ody of the subdivisions were ruptured or distorted, whereas by the employment of a series of straight blades which consecutively act upon the web according to the principle of my invention, cleanlongitudinal incisions of the web are produced without appreciable distortion of the material between successive blades. It is also to be noted that in the case of a multiplicity of spaced-apart circular blades having a common axis of rotation, the lateral pressure of the subdivided material against the opposing blades, owing to the thickness of the latter, tends to bend the blades and to cra'mpand bind the interposed match stock.

I claim 1. The combination with means for feeding sheet match stock, of a revoluble cutter having its axis of rotation longitudinally of the path of the stock and having a series of spaced. apart peripheral blades parallel to said axis, and means for effecting cooperative relative movement between the said cutter and the stock, transversely ofthe latter, whereby the blades operate consecutively to incise the stock inparallel longitudinal splint mes. a

means for timing the said cutter in relation to the stock.

- 3. The combination with means for feeding stock, said cutter including a series of spaced apart peripheral blades parallel to said axis, whereby during each stroke of the carriage the blades consecutively incise the stock in parallel longitudinal lines, and gear and rack means operative to ensure the proper registry or timing of the cutter in relation .to the stock.
